In most of our Solr use-cases, we fetch only fl=<uniqueKey> or fl=<uniqueKey>,<another_int_field>. I'd like to be able to do a distributed search and skip STAGE_GET_FIELDS -- i.e. the stage where each shard is queried for the documents found the the top ids -- as it seems like we could be collecting this information earlier in the pipeline.
Is this possible out-of-the-box? If not, how would you recommend implementing it? Thanks! --Gregg
